We back up EVERYTHING we shoot… and it’s ALOT of tape. A typical season of one of our shows will generate anywhere from 1500 to 3500 HOURS of video. Every second of that is copied while the masters are retained in a vault until the season has completed airing. Then, the copies are recycled and used to back up the next season. I am less concerned about the obvious risks like fire, flood or earthquake, and more about the more common problems of losing or damaging a tape (disc). Since our backups are now clones, that concern has evaporated.
As for shipping master tapes from the field, it depends on the location and the length of the shoot. Typically, there is too much material to dub on location and the masters are travelling unprotected. This would be the same as a film shoot where the “dailies” have to travel to the lab for processing. For that first leg of the trip, there can be no backup. That’s why you buy production insurance!
While we’re on the subject, we also back up the PROJECT info to at least three places: locally, globally (networked storage) and mobilly (usb memory stick). It just makes sense to take these precautions, ’cause the minute you don’t is the exact moment a disaster will occur.
